Introduction
The evo HE is a wall mounted, room sealed, condensing
combination boiler, featuring full sequence automatic spark
ignition and fan assisted combustion.
Due to the high efficiency of the boiler, condensate is produced
from the flue gases and this is drained to a suitable disposal point
through the plastic waste pipe at the lower rear of the boiler. A
condensate 'plume' will also be visible at the flue terminal.
The evo HE is a combination boiler providing both central heating
and instantaneous domestic hot water.

BOILER CONTROLS
Summer conditions - i.e. DHW only required.
Set the thermostat knob to OFF.
The boiler will fire periodically for a few seconds to maintain the
DHW calorifier in a preheated condition. The average time
period between firing is 90 minutes. This may vary considerably
due to the surrounding ambient temperature of the boiler. The
boiler will fire whenever there is a demand for DHW.
Note. The pump will operate briefly as a self-check once every
24 hours, regardless of system demand.
Control of water temperature
Domestic Hot Water
The DHW temperature is limited by the boiler controls to 65oC
maximum at low draw-off rate, adjustable via the DHW
thermostat knob (J).
Due to system variations and seasonal temperature fluctuations
DHW flow rates/temperature rise will vary, requiring adjustment
at the draw off tap : the lower the rate the higher the temperature,
and vice versa.
Central Heating
The boiler controls the central heating radiator temperature to a
maximum of 82oC, adjustable via the CH thermostat knob (F).
To shut down the boiler
1. For short periods
Set the mains ON/OFF switch (A) to OFF
2. For longer periods
Set the mains ON/OFF switch (A) to OFF, and switch the
electricity supply to OFF. For longer periods the entire system
should be drained.
To relight the boiler
Repeat the procedure detailed in 'To light the boiler'.
Frost protection
If no frost protection is provided and frost is likely during a short
absence from home, leave the heating controls (if fitted) at a
reduced temperature setting. For longer periods, the entire
system should be drained.
If the system includes a frost thermostat then, during cold
weather, the boiler should be turned OFF at the time switch (if
fitted) ONLY. The mains supply should be left switched ON, with
the boiler thermostat left in the normal running position.
Boiler overheat thermostat
This thermostat will shut down the boiler in the event of
overheating. Should this occur a fault code or will be
displayed. Press the reset button (D) and the boiler will relight.
If the fault recurs, turn off the boiler and consult a Gas Safe
Registered Engineer or in IE a Registered Gas Installer (RGII).
Flame failure
Should this occur a fault code will be displayed.
Press the rest button (D) and the boiler will relight.
If the fault recurs, turns off the boiler and consult a Gas Safe
Registered Engineer or in IE a Registered Gas Installer (RGII).
Loss of system water pressure
The gauge (H) indicates the central heating system pressure. If
the pressure is seen to fall below the original installation pressure
of 1-2 bar over a period of time then a water leak may be
indicated. In this event conduct the re-pressurising procedure
(see Trouble Shooting - Problem 4). If unable to do so or if the
pressure continues to drop a Gas Safe Registered Engineer or
in IE a Registered Gas Installer (RGII) should be consulted.
DO NOT FIRE THE BOILER IF THE PRESSURE HAS
REDUCED TO ZERO FROM THE ORIGINAL SETTING.
Condensate Drain
The condensate drain (G) must not be modified or blocked.
Blockage of the condensate drain, caused by debris or freezing,
can cause automatic shutdown of the boiler.
If freezing is suspected and the pipe run is accessible an attempt
may be made to free the obstruction by pouring hot water over
the exposed pipe and clearing any blockage from the end of the
pipe. If this fails to remedy the problem the assistance of a Gas
Safe Registered Engineer or in IE a Registered Gas Installer
(RGII) should be sought.
Escape of gas
Should a gas leak or fault be suspected contact the National Gas
Emergency Service without delay. Telephone 0800 111 999
Do NOT search for gas leaks with a naked flame.
Cleaning
For normal cleaning simply dust with a dry cloth.
To remove stubborn marks and stains, wipe with a damp cloth
and finish off with a dry cloth.
DO NOT use abrasive cleaning materials.
Maintenance
The appliance should be serviced at least once a year by a Gas
Safe Registered Engineer or in IE a Registered Gas Installer
(RGII).

POINTS FOR THE BOILER USER
Note. In line with our current warranty policy we would ask that you check through the following guide to identify any
problems external to the boiler prior to requesting a service engineers visit. Should the problem be found to be other than
with the appliance we reserve the right to levy a charge for the visit, or for any pre-arranged visit where access is not
gained by the engineer.
TROUBLESHOOTING - TYPICAL NON PRODUCT FAULTS
Problem Solution
Boiler is not working for
central heating or hot water.
• Check there is power to the boiler – switch (A) in the ON position and ‘
0
’displayed on the
controls.
•If‘
0
’ not displayed then not a boiler fault – contact your installer/service company.

(flashing).
• Press reset button (D) for 2 seconds, the boiler should then re-light. If fault recurs this indicates
an overheat condition. The boiler should be turned off and your installer contacted.
• Check if ALL radiators have thermostatic radiator valves fitted. If they have contact your
installer.

(flashing).
• Check pressure gauge on boiler shows a minimum of 1 bar. If not re-pressurise via the filling
loop to 1 bar (if unsure contact your installer), turn off the tap on the filling loop and turn the on/
off switch (A) off and then back on again to reset the boiler. If unable to do so or if the pressure
continues to drop after filling then contact your installer.
• Check if ALL radiators have thermostatic radiator valves fitted. If they have contact your
installer.
Boiler is not working for central
heating or hot water but
attempts to fire by going
through 3 ignition attempts.
Display shows ‘

’(flashing).
• Press reset button (D) for 2 seconds to repeat ignition sequence.
• Check gas supply (try another appliance – cooker/fire etc.) – If no gas supply then not a boiler
fault – contact gas supplier.
• Check condensate pipe is not blocked or frozen. If blocked clear blockage – if not possible to
check contact your installer.
Boiler will not fire for central
heating.
• Check external programmer is set to an ‘ON’ period.
• If already set to an ‘ON’ period then check the programmer by setting to continuous if boiler then
fires – Contact your installer to rectify the programmer.
• Check room thermostat by turning fully up, If ‘0’ is not displayed on the user controls then
contact your installer.
Boiler comes on for domestic
hot water without a tap being
opened - the display shows
‘D’.
• Check for dripping / dribbling taps or showers – turn fully off.
• Check for leaks from the domestic hot water pipework and if found contact your installer.
Boiler fires occasionally for
approx. 2 minutes - the
display shows ‘t’.
• This is a normal function of the boiler to periodically pre heat the plate heat exchanger to
optimise delivery time for domestic hot water to taps or showers.
The nature of all combination boilers is to heat up water directly from the incoming mains water supply directly through the boiler to
supply domestic hot water at the stated flow rates, (as shown in the boiler installation instructions), to achieve a 35oC temperature
rise. As the ambient temperature of the cold main varies during the summer and winter months it is likely in the colder winter months
that the flow rate will need to be reduced at the outlet taps to achieve the same temperatures achieved in the warmer summer
months. This is not a fault with the appliance but is relevant to the varying temperature of the incoming cold mains water
supply.
